• Extremely accurate in very low temperature ranges, i.e. cold storage rooms
• Optional connectable temperature sensor and wireless sensor for different applications in the field
• Audible alarm, user-defined thresholds
• HACCP compliant, certified according to EN 13485 for use in the food sector

 

• High-resolution colour display for the graphic representation of your measurement data
• Extended measurement menus - such as gas pipe testing - for a comprehensive analysis of your heating system
• Logger function for easy long-term recording of the measurement curve
• Graphic processing of measurement data

 

• Unique hook-on function separates and grabs wires, without using your hands
• Retractable post makes hook release fast and easy
• Inrush (starting) current capture, APO (Auto Power Off), and Min / Max / Hold

 

• Long battery life of up to 500 consecutive days of use with a large memory capable of storing 64,000 readings
• Replaceable battery for unlimited use
• PDF Reports allow for quick access to non-corruptible documentation - without installed software!
• NFC (Near Field Communication) allows for easy access of documentation with a compatible device

 

• Integrated differential pressure sensor with an accuracy of 0.2 % of f.v.
• Calculation of the flow velocity and the volume flow via Pitot tube (optional)
• Multi-point and timed mean calculation
• 2 probe inputs for additional pressure and temperature probes

 

• Unique hook-on function separates and grabs wires, without using your hands, and the retractable post makes hook release in tight spaces fast and easy
• Bluetooth, coupled with the free testo Smart Probes app, works with smartphones and tablets for remote viewing, data logging, and report creation

• 640 x 480 SuperResolution images using included IRSoft analysis
• Large 4.3" rotating touchscreen display
• 2GB SD card for storage included
• Optional lens protection glass

 

• Measures air velocity, volume flow, and temperature, as well as air flow at registers, and automatically calculates volume flow (simply enter the duct dimensions)
• No air density correction required, due to its design
• Measure volume flow at several outlets simultaneously (using mutiple Smart Probes), to adjust system balance
• Timed/multipoint averaging to get accurate air flow profiles
